I'll be down to work on the 3D printer and Kicad. To finish the printer, I
am in need of 2 precision-sized springs, specifically:

2x 12mm OD and made of 8 turns of 0.9mm zinc-plated spring steel wire. The
free length is 30mm

I forgot to order them and it might be fun to actually make these using a
slow drill and some spring wire. Does anyone have any spring wire or know
where I can get some this eve? A thread of steel rope (e.g. from as
bikelock cable) [1] or music wire(?) [2] are another options.

Cheers,
Ed

P.s. Maplin / Screwfix don't stock anything useful.
